 ## ToDo and wanted features:
+- [ ] Integrate CIDStorage library to the Dapp Indexer smart contract
 - [ ] Create an event for metadata information about the CID.
-- [ ] Support other type of hashes or structure storage

 ### Deploy
 
+#### Option1: Deployment script (recommended)
+
 ```shell
-$ forge script script/Counter.s.sol:CounterScript --rpc-url <your_rpc_url> --private-key <your_private_key>
+$ ./deploy.sh 
 ```
+> IMPORTANT: verify .env information before executing the  deployment script
+
+**verify by attaching the deployed contract test:**
+
+Once you deployed the contract with the previous script execution you can test
+the correct smartcontract operations by running the `DeployedDappIndexer.s.sol`
+script
+
+should set after deploying the smart contract in the .env named after 
+DAPPINDEXERADDRS, once you update the address you can run the following
+script to verify it was deployed correctly.
+
+```shell
+$source .env
+$forge script script/DeployedDappIndexer.s.sol:DappIndexerScript --fork-url $PROVIDER_URL --private-key $PK0 --broadcast 
+```
+#### Option2: Script deployment and test 
+using the script follows diferent verifications first before deploying the
+contract, more about it here.
+
+```shell
+$source .env
+$forge script script/DappIndexer.s.sol:DappIndexerScript --fork-url $PROVIDER_URL --private-key $PK0 --broadcast
